Morning Musume uses the word "sexy" but it's not like they are overly sexy and wear tight body suits (e.g. Sparkle)
I have kind of built up 'respect' for Ayu because of her diva-ish nature and her elegance. I know she's a grown woman and what not, but if she starts talking about sex and that sort of thing, Ayu will definitely lose me as a fan
I like those things to be kept private... I don't really like it when singers blurt out crap like "lick me" and other overtly sexual things.
